Title: Production of 2,2,4,6,6-pentamethylheptane-4-thiol
Inventor: MATSUOKA RIKITARO
IPC: C07C319/04
Filed: 1994-12-27
Abstract: PURPOSE:To obtain 2,2,4,6,6-pentamethylheptane-4-thiol in high purity and yield by using recovered triisobutylene having poor reactivity. CONSTITUTION:Triisobutylene containing a Lewis base as an impurity is treated with an acid and then reacted with hydrogen sulfide in the presence of a Lewis acid or reacted with hydrogen sulfide in the coexistence of a Lewis acid and a protonic acid to obtain 2,2,4,6,6-pentamethylheptane-4-thiol of the formula. It is preferable to use 0.01-0.5mol of Lewis acid and 0.005-0.5mol of protonic acid based on 1mol of triisobutylene. The reaction is carried out at 2-30atm, especially 3-15atm and -100 to +50 deg.C, especially -40 to +10 deg.C. The yield of the objective compound can be improved by contacting a reaction stopper with the reaction liquid after the reaction to stop the reaction.

Title: Damping pad for preventing brake noise
Inventor: FURUSU KATSUYA
IPC: F16D65/097
Filed: 1990-11-30
Abstract: PURPOSE:To suppress brake noise in a wide temperature range by providing damping materials whose temperature ranges for good damping performance are different from each other, between a first metal plate which has a brake shoe fixed thereto and the second and third plates of the same shape as that of the first one. CONSTITUTION:A brake friction pad 8 includes a first metal plate 6 which has a brake shoe 7, fixed thereto and the second and third metal plates 2, 4 of the same shape as that of the first one. A first damping layer 1 and a second damping layer 3 are inserted and between the aboved-mentioned first and second metal plates as the elastic body having the maximum of lost factor values in the temperature range form 50 deg. to 100 deg.C and between the second and third plates 2, 4 as the same elastic body in the temperature range from 0 deg. to 30 deg.C  deg.F respectively. Even if the brake shoe 7 generates heat and the heat and its vibration are transmitted to the first metal plate 6, the brake noise in a high temperature range is suppressed in the above- mentioned first damping layer 1. Since a viscoelasticity body has small heat conductivity, the second metal plate 2 is kept at a low temperature, and the brake noise in a low temperature range is, therefore, suppressed in the above-mentioned second damping layer 3.

Abstract: PURPOSE:To reduce the distortion of a signal wave in an inner wiring part, and prevent the decrease of assembling yield, by bonding a substrate member having a multilayer wiring pattern wherein semiconductor elements are subjected to fixing, mounting, and bonding, to a lead frame. CONSTITUTION:A semiconductor element 1c is fixed by using wax material on an island part 1g of a substrate (a) provided with a desired multilayer wiring pattern. The element 1c and the substrate are subjected to lead-bonding by wire connection or the TAB system. Further the element is connected with outer terminals 1c of the lead frame by using outer leads (g). After resin sealing, the outer terminals are cut off and shaped. Hence a large part of an inner wiring can be matched with the characteristic impedance of the element, so that the distortion of signal waveform is restricted within a small value. In addition, the inner lead part which is microminiaturized and lengthened as the result of multipin structure can be shortened, and the decrease of assembling yield caused by the deformation of the inner lead can be prevented.

Abstract: PURPOSE:To obtain an element separation region in spacer width by performing ion-implantation of boron for a transfer electrode which is formed by a poly Si, etc., and phosphor to a side wall insulation film which is formed on a side wall of the transfer electrode in self-aligned manner. CONSTITUTION:A transfer electrode 4 is used as a mas and boron B is ion- implanted to a substrate 6, thus forming a p<+> region. Then, an SiO2 film 8a is deposited on an entire surface by the CVD method, etc., and then etchback is performed, thus enabling the SiO2 film 8 to remain on a side wall of the transfer electrode 4. After that, the side wall insulation film 8 which is located at an opposite side of an element separation side is eliminated. Then, using the SiO2 film which remains on this side wall as a mask and performing ion- implantation of a phosphor P, an n<+> region is formed. Then, a region where P is ion-implanted becomes an n<+> type accumulation diode 1 and only a region below the side wall insulation film 8 where B rather than P is implanted becomes a p<+> type element separation region 3.

Abstract: PURPOSE:To reduce the frequency of power supply of a solenoid valve by opening a first stage solenoid valve when the temperature of discharge gas exceeds a specified value and opening a second stage solenoid valve when the temperature further rises and reaches a specified value. CONSTITUTION:When the temperature of discharge gas of a compressor exceeds a specified value, a first stage solenoid valve 5 is opened where the refrigerant whose pressure is reduced by a capillary tube 7 is sprayed so that the discharge gas may be cooled on the way of compression process. Furthermore, when a first stage bypass volume is insufficient and the temperature of discharge gas exceeds the next specified value, a second stage solenoid valve 6 is opened so that the gas may be sprayed in the same manner with a capillary tube 8 and cooled. In this manner, the temperature of discharge gas is set to two stages so that a two sage-based bypass circuit may be formed with the capillary tubes 7 and 8, thereby forming a bypass circuit of a proper amount of refrigerant. This construction makes it possible to set proper the refrigerant bypass volume and reduce the frequency of power supply of each of the solenoid valves 5 and 6.
